A while back I was asking about round balers. 

 I found a Claas rollant 46, which I was told is a silage baler?

 What I would like to figure out, is how much hp the baler itself needs? Not the tractor size, but the hp requirements to run the baler? As in if an engine were hooked directly to the baler, minus the tractor, what minimum hp engine would run the baler? Conditions would be non production, light windrow of weeds, but no dry down. I dont even want to make even size bales, I wish to drop the bale at the same spot on the field each time reguardless of bale size.

 Thanks.
